The Gandhian crusader also claimed that Kejriwal should be booked if his charges against Vadra prove wrong. Even Kejriwal, a former RTI activist, also asserted that he would be ready to face defamation case if Vadra proves charges against him as false.

Hours after Kejriwal's corruption charges against the son-in-law of the Gandhis, the septuagenarian said, "If allegations (against Vadra) levelled by Arvind are false, then order a probe and let the facts speak. If the allegations are false, file a case against Arvind Kejriwal."

Anna's statement supporting Kejriwal surfaced at a time when Congress President Sonia Gandhi asked her party members to defend her son-in-law. Citing Mrs Gandhi's order, Congress leaders such as Law Minister Salman Khurshid, Information and broadcasting minister Ambika Soni have begun defending Vadra.

Khurshid claimed that Kejriwal along with Bhushan has been trying to hog limelight with such "baseless" comments and also termed allegations against Vadra as "political conspiracies".

Ambika Soni said, "It is for the entity that gives loan to decide the terms of loan. It is between the two individuals". Congress leader Rajiv Shukla also joined the list of ministers and Congress leaders who have come out in open to defend the son-in-law of the Gandhis.

"All businessmen take loans to build their business. Maybe Robert Vadra also did that. What is wrong with that? But there is nothing to prove any wrong-doing...no proof that the Congress helped out DLF," said Shukla.

The former Team Anna members and RTI activist also said six firms had been registered so that land worth Rs 300 crore was transferred in the name of Vadra. Continuing his statement accusing Vadra of corruption, Kejriwal also stated that he was surprised to see that the DLF provided the loan to buy property mostly in Congress-ruled states of the country.

However, countering Kejriwal's charges against Vadra, Shukla said, "There was no quid pro quo. There was no favour given to DLF which is working in all states and has bought land even in non-Congress-ruled states."

Meanwhile, DLF also issued a statement saying, "The business relationship of DLF Group with Robert Vadra has been in his capacity as an individual entrepreneur and on a completely transparent and arm's length basis."
